++Subject has taken galantamine or memantine within 60 days prior to screening++Clinically significant abnormal laboratory values at screening++History of any significant neurologic disease other than Alzheimer's disease, including Parkinson's disease, multi-infarct or vascular dementia, Huntington's disease, normal pressure hydrocephalus, progressive supranuclear palsy, multiple sclerosis, seizures++Mental retardation++History of significant head trauma followed by persistent neurologic deficits or known structural brain abnormalities++Clinically significant uncontrolled medical or psychiatric illness.

This is a Phase II study designed to evaluate the efficacy and safety of ABT-126 in older adults with mild to moderate Alzheimer's disease who are taking stable doses of acetylcholinesterase inhibitors. Participants will be randomized to receive one of two ABT-126 doses or a placebo for a 24-week treatment period. Participants in this study may be eligible to take part in a related extension study; see NCT01690195 in for details.
